y = x^2 - 4x + 4
Find the discriminant.
Determine the number
of real solutions.

Answers

Answer 1

Answer:

The discriminant is 0

There is 1 real solution

Step-by-step explanation:

Use the discriminant formula, D = b² - 4ac

In the equation y = x² - 4x + 4, a is 1, b is -4, and c is 4.

Plug in these values into the formula:

D = b² - 4ac

D = (-4)² - 4(1)(4)

D = 16 - 4(4)

D = 16 - 16

D = 0

So, the discriminant is 0.

With a discriminant of zero, there is one real solution.

So, the number of real solutions is 1.

420cm^3 (cubed) = volume when tripled

Step-by-step explanation:

1. when you multiply 7*4*5=140 (volume of the prism originally)

2. 140*3=420 (final answer)

Answer:

A. 140 cm

B. 3780 cm

Step-by-step explanation:

The volume formula for a rectangular prism is lwh, and 7 times 4 times 5 equals 140.

If you triple all those amounts, then you get 21 (7 times 3), 12 (4 times 3), and 15 (5 times 3), and when you multiply those you get 3780.

Khan uses 78 feet of fence to make a rectangular pen for his pet rabbit. The length of the pen is 25 feet what is the width of the rectangular pen

Answers

The width of the rectangular pen is equal to 14 feet.

Given the following data:

Perimeter of rectangle = 78 feet.Length = 25 feet.

To calculate the width of the rectangular pen:

A circular plate has circumference 33.3 inches. What is the area of this plate? Use 3.14 for Pi.
The area of this plate is_____about square inches.
(Round the final answer to the nearest whole number as needed. Round all intermediate values to the nearest
thousandth as needed.)

Answers

Answer:

88 square inches

Step-by-step explanation:

A circular plate has circumference 33.3 inches.

Step 1

We find the radius

The formula to find the radius go a circle given circumference is

= C /2π

r = 33.3/2 × 3.14

r = 5.3025477707 inches

Approximately to the nearest thousandth = 5.303 inches

Step 2

What is the area of this plate? Use 3.14 for Pi.

The area of a circle = πr²

Where

π = 3.14

r = 5.3025477707 inches

Hence

Area of the circle = 3.14 × (5.303inches)²

= 88.30248026 square inches

Approximately to the nearest whole number the area of the circle = 88 square inches

The area of this plate is about 88 square inches.

In circle L with m^KLM 54 and KL= 10 units, find the length of arc KM.

Round to the nearest hundredth.

Answers

Given:

In circle L, measure of angle KLM is 54 degrees and KL = 10 units.

To find:

The length of arc KM.

Solution:

The formula for arc length is:

[tex]s=2\pi r\times \dfrac{\theta}{360^\circ}[/tex]          ...(i)

Where, r is the radius of the circle and [tex]\theta [/tex] is the central angle in degrees.

The measure of KL is 10 units, it means the radius of the circle L is 10 units.

The measure of angle KLM is 54 degrees, it means the measure of central angle on arc KM is 54 degrees.

Putting [tex]\pi=3.14, r=10,\theta=54^\circ[/tex] in (i), we get

[tex]s=2(3.14)(10)\times \dfrac{54^\circ}{360^\circ}[/tex]

[tex]s=20(3.14)\times 0.15[/tex]

[tex]s=9.42[/tex]

Therefore, the length of arc KM is 9.42 units.
